How it works
Upload, confirm the estimate, then export.
Upload a recording, approve the estimate, download your book.
A conversion runs as a pipeline: we transcribe the audio, read the slides for figures, organize everything into chapters, write the prose, and typeset the result. You see the cost and time estimate before any billed processing starts, and the final draft is yours to edit and export.
Upload once, review estimate ranges, and confirm before conversion starts.
Track queued, processing, finalizing, and completion states as they happen.
Refine structure/content and export PDF or ePub from the same project.
Inside a conversion
What the pipeline does.
Five stages take your recording from audio to a typeset book.
Stage 1
Transcription
The recording’s audio is transcribed into accurate text, with speaker narration kept intact as the backbone of the book.
Stage 2
Slide reading
Frames are captured from the video and read for figures, diagrams, and on-screen text, so the visuals from your deck can be placed into the book.
Stage 3
Structuring
The transcript is organized into chapters and sections that follow the arc of the lecture, with key terms pulled out as definitions.
Stage 4
Drafting
Each section is written into readable prose at the quality tier and prose style you choose — from concise notes to fuller chapters.
Stage 5
Typesetting & export
Figures are captioned and placed next to the relevant text, and the whole book is typeset into a PDF and an ePub you can download and keep editing.
Improves with
- Clear audio and minimal background noise.
- Readable slides and stable framing.
- Narration that follows slide order.
Still works when
- Slides are sparse but narration is strong.
- There are brief interruptions.
- You plan to edit and refine output.
Where you'll still do work
- The draft is a strong first pass, not a final edit — give it a quick review before you publish.
- Unusual or low-quality sources may need extra editing.
